pub fn load_and_exec(req: &KexecRequest) -> Result<Infallible, KexecError>Expand description
Load the requested kernel via kexec_file_load(2) and immediately trigger
reboot(LINUX_REBOOT_CMD_KEXEC).
On success this function does not return — the calling process is
replaced by the new kernel. Returning Ok with std::convert::Infallible
is unreachable in practice; the type signature documents the intent.
§Errors
See KexecError — every non-success path is classified so the caller
can present a specific diagnostic.
